Tuning RubyMine

Changing RubyMine properties
RubyMine makes it possible to change *.vmoptions
and
idea.properties
files without editing them in the RubyMine installation folder.
To create an empty idea.properties
file or to copy
*.vmoptions
file, choose
the or
on the main menu respectively. Refer to the
menu items description for details.
Managing *.vmoptions file
For Mac OS X systems: The file/Applications/RubyMine XX.app/Contents/bin/rubymine.vmoptions
should be copied to ~/Library/Preferences/RubyMine XX/rubymine.vmoptions
For the older versions, the settings are stored in
/Applications/RubyMine <version>.app/Contents/Info.plist
.
To avoid editing files in the RubyMine installation folder, one should:
- Do one of the following:
- Copy the existing file from the RubyMine installation folder somewhere and save the
path to this location in the environment variable
RUBYMINE_VM_OPTIONS
. - Copy the existing file
<RubyMine installation folder>/bin/rubymine$BITS.vmoptions
from the RubyMine installation folder into the location under user home:- For *NIX:
$HOME/.RubyMine XX/rubymine$BITS.vmoptions
- For Windows:
%USERPROFILE%\.RubyMine XX\rubymine%BITS%.exe.vmoptions
The value of the variable BITS depends in the JVM used to run RubyMine:
Refer to the support article Selecting the JDK version the IDE will run under for details.
- For *NIX:
- Copy the existing file from the RubyMine installation folder somewhere and save the
path to this location in the environment variable
- Edit this file in the new location.
If RUBYMINE_VM_OPTIONS
environment variable is defined, or the
*.vmoptions
file exists,
then this file is used instead of the file located in the RubyMine installation folder.
Example: Increasing the heap size
To increase RubyMine heap size, you should copy the original rubymine.vmoptions
file to the
above-mentioned location, and then modify the -Xmx
setting.
Managing IDEA.properties file
The file idea.properties
, located in the bin
directory of the RubyMine installation folder, should not be edited. Instead of editing the original
idea.properties
, create file idea.properties
in the location specified below, open it for editing and add the required
properties.
So, depending on your platform:
- For Windows: in
%USERPROFILE%\.RubyMine XX
- For *NIX: in
~/.RubyMine XX
- For Mac OS X: in
~/Library/Preferences/RubyMine XX
Example: Changing case of unicode literals
RubyMine allows defining whether non-ascii characters should use literals like '\u00AB'
or '\00ab'
.
This behavior is controlled by the system property idea.native2ascii.lowercase
. By default,
upper case characters are used.
If it is desirable to use lower case characters, create the file idea.properties
in the location specified above, open it for editing and add the following line:
idea.native2ascii.lowercase=true
Specifying custom JDK, properties or vmoptions files across platforms
A custom JDK, *.properties
and *.vmoptions
files are specified across platforms in
a unified way.
All the launchers look at the following environment variables:
